Question

11. When the volume of a gas increases at constant temperature: the average kinetic energy stays the sameB - the mean square velocity stays the same the frequency of collisions decreases the force per collision decreases Incorrect. Submit 12. When the moles of a gas increase at constant volume and tempera the average kinetic energy increases the mean square velocity stays the same - the frequency of collisions increases the force per collision increases Incorrect. Submit 13. When hydrogen gas is replaced by nitrogen gas: - the average kinetic energy stays the same the mean square velocity decreases the frequency of collisionsstays the same the force per collision stays the same Incorrect.

Answer 1

Average kinetic energy = 3/2 RT/N mean square velocity v^2_rad = 3 RT/MN frequency of collisions f = v/lambda (v_max) force per collision f = (m/d) v_x^2 Using these formulas and comparing them with given questions we get 1) stays the same 2) stays the same 3) stays the same 4) decreases 1) decreases 2) decreases 3) decreases 4) stays the same 1) stays the same 2) decreases 3) decreases 4) Increases
